I know they should hire a giant sky writer and spell it out for all of NZ to see! Or maybe they should hire a blimp with a billboard on it saying there is an outage! They should have organised a mail drop in the areas impacted!

Twitter and online sources are the fastest way of communicating since not all their customer base was taken offline. If they went on any other outbound communication medium it wouldn't have been communicated at all.

We used twitter, web, Facebook and our call centre messages to inform customers, many have told me they access those sites for information on mobile devices. The brief outage period means the only way of informing customers is these, traditional media won't get the information out fast enough.
